Chondroradionecrosis of larynx following radiotherapy for metastatic neck disease originating from oral carcinoma.

Chondroradionecrosis of larynx is a rare but serious complication of radiotherapy. Here is described a case of chondroradionecrosis after 20 years of completion of radiotherapy for oral cancer. The patient underwent excision of necrotic anterior skin of the neck, together with devitalized thyroid cartilage and most of the cricoid cartilage, and reconstruction with pectoralis major muscle transposition. This resulted in preservation of laryngeal function, and avoided further exploration of the irradiated neck and possible further skin loss.
